Write a Java-program to print sum of Odd numbers using for loop ?

Program

public class Main
{
    public static void main(String args[])
    {
        int x,n=5,sum=0;
        for(x=1; x<=n; x++)
        {  
            if(x%2!=0)
            {
                sum=sum+x;    
            }
            
        }
        System.out.print("Odd numbers sum is: "+sum);
    }
}	

Odd numbers sum is : 9

Using CommandLine Arguments

public class Main
{
    public static void main(String args[])
    {
        int x,n,sum=0;
        n=Integer.parseInt(args[0]);
        for(x=1; x<=n; x++)
        {  
            if(x%2!=0)
            {
                sum=sum+x;    
            }
            
        }
        System.out.print("Odd numbers sum is: "+sum);
    }
}	

Odd numbers sum is : 9

Using Scanner Class

import java.util.*;
public class Main
{
    public static void main(String args[])
    {
        int x,n,sum=0;
        Scanner s=new Scanner(System.in);
        System.out.println("Enter n value: ");
        n=s.nextInt();
        for(x=1; x<=n; x++)
        {  
            if(x%2!=0)
            {
                sum=sum+x;    
            }
            
        }
        System.out.print("Odd numbers sum is: "+sum);
    }
}
